The Power Of CTRL+T

Did you know that you can check what a process is doing by pressing CTRL+T?
Has it happened to you before that you were waiting for something to be finished that can take a lot of time, but there is no easy way to check the status. Like a dd, cp, mv and many others. All you have to do is press CTRL+T where the process is running. This will output what’s happening and will not interrupt or mess with it in any way. This causes the operating system to output the SIGINFO signal.
On FreeBSD it looks like this:

As you can see it not only outputs the name of the running command but the following parameters as well:
94371 – PID
4.70r – since when is the process running
0.00u – user time
0.00s – system time
0% – CPU usage
2500k – resident set size of the process or RSS
